Referring to the drawing, the numeral 1 shows a fragment of a conventional type of hand set combination telephone receiver and transmitter. The mouthpiece is indicated by the numeral 2 and has a perforate diaphragm 3 forming part of the housing enclosing the transmitter mechanism. A holder t comprises an annulus or rim A holder for a renewable antiseptic disc adapted to be attached to a telephone transmitter of the perforate diaphragm type comprising: an annular rim having a plurality of tapered pegs projecting from one face, said pegs being circumferentially spaced to align with the perforations in the diaphragm, and being of a length and thickness to enter and wedge in the perforations of the diaphragm; stop means projecting from the rim to =5 hav tapered p gs 6 extending therefrom, age the face of the diaphragm and limit penewhich are adapted to wedge into the perforations tration of the pegs into the perforations; and a l in the diap ragm 3 0 re a ly retain the grid formed integral with the rim to retain an ho in position.
